Brain tumour surgery
Maximum safe resection of brain tumours using neuronavigation, awake craniotomy and continuous neurophysiological monitoring to protect neurological functions.
A different approach for every tumour
In brain oncology no two tumours are alike. The surgical plan depends on the histological type, location, relationship with eloquent areas and the patient's condition. Each case is assessed by a multidisciplinary board before the strategy is decided.
Symptoms of brain tumours
The symptoms of a brain tumour depend on its size, its rate of growth and, above all, its location. They may be caused by increased pressure within the skull or by direct involvement of a specific brain area.
General symptoms (due to raised intracranial pressure)
- Progressive headache, predominantly in the morning, worsening over time and with manoeuvres such as coughing or bending.
- Nausea and vomiting, sometimes without prior nausea ("sudden-onset vomiting").
- Drowsiness or slowing of the level of consciousness.
- Blurred or double vision and papilloedema on fundoscopy.
Focal symptoms (according to location)
- New-onset seizures (first seizure in an adult with no prior history).
- Focal neurological deficit: weakness or numbness on one side of the body.
- Speech disturbance (difficulty speaking or understanding).
- Visual disturbance or visual field defect.
- Unsteadiness, lack of coordination or gait disturbance (posterior fossa or cerebellar tumours).
Cognitive and behavioural changes
- Short-term memory loss and difficulty concentrating.
- Personality changes, apathy or irritability.
- Disorientation and slowed thinking.
Brain tumours we treat
Gliomas
Low- and high-grade. Maximum safe resection with neuronavigation, awake craniotomy and neurophysiological monitoring.
Meningiomas
Complete microsurgical resection with low recurrence rates. Preservation of adjacent vascular structures.
Acoustic neuromas
Skull base approaches with hearing and facial nerve preservation in selected tumours.
Maximum precision, preserved function
- Neuronavigation: high-resolution brain GPS to guide every millimetre.
- Awake craniotomy: real-time functional mapping in tumours within eloquent areas.
- Continuous neurophysiological monitoring: protection of speech, movement and cranial nerves.
- 4K/3D microscopy and intraoperative MRI when indicated.
- Multidisciplinary board: neurosurgery, neuro-oncology, neuroradiology and pathology working together.
MRI-guided laser ablation for brain tumours
Laser interstitial thermal therapy (LITT) has become established as an alternative or complement to open surgery in selected oncological scenarios. It does not replace maximum safe resection when that is feasible: it is one more tool, particularly useful when the lesion is deep, surrounded by eloquent areas, the patient is not a candidate for craniotomy, or when treating a recurrence without reopening a previously operated or irradiated field.
Glioblastoma and high-grade gliomas
Growing indication in recurrent GBM and in primary deep non-resectable cases. Modern series report an acceptable safety profile and survival data comparable to alternative rescue strategies4-8.
Brain metastases and radionecrosis
Particularly useful in recurrences after radiosurgery and in symptomatic radionecrosis refractory to corticosteroids. Ablation allows treatment of the lesion and, in many cases, histological distinction between tumour recurrence and necrosis9-11.
Deep or complex-location lesions
Insular, thalamo-mesencephalic or posterior fossa tumours where conventional microsurgical approach would carry high functional morbidity. The stereotactic trajectory reaches the target while minimising the lesioned corridor12,13.
Patient not suitable for craniotomy
Advanced age, comorbidity, history of multiple surgeries or prior irradiation. LITT offers a minimal-incision profile (4 mm), short stay and lower infection risk, with real-time thermal control via intraoperative MRI.

What our patients say
"I arrived with a glioma I had been told was inoperable. Here they reviewed it at the tumour board and offered me a plan. The surgery was a success. Four years on, I am well."
"For years I had a cervical disc herniation, operated on by another team with no improvement. Minimally invasive surgery gave me back my mobility and took the pain away."
"I travelled from outside Spain. The team reviewed my case before I came and gave me a clear plan. Caring people and impeccable technique."
